.FAN ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 744,600, dated November17, 1903. Application filed May 15, Serial No. 157,256. (No model.)

To all whom it may concern:

Be it known that I, OTTO G. OGDEN, a citi-- zen of the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have made certain new and useful Improvements in FanAttachments for Sewing-Machines, of which the following is i of thefan-wheel to secure a compact arrangement of the parts for shipment orstorage; and the invention consists in certain novel constructions andcombinations of parts hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of the invention as inuse. Fig. 2 is a detail perspectiveview of the hub or disk with theconnecting-arms in place and adjusted in full lines to project laterallyfrom one side of the hub and in dotted lines to project from theopposite side of the hub. Fig. 3 is a detail perspective view of the huband connecting-arms with the latter adjusted into 'the plane of the hub.Fig. 4 is a detail perspective view of one of the connecting springarms,and Fig. 5 is a detail perspective view of one of the fan-shanks.

, Incarrying out my invention I provide in connection with thehub A theblades B and their shanks G, connecting-rods E for-securing the hubdetachably in connection with the fly-wheel F of the sewing-machine, andas this fiy-wheel F is sometimes turned in one direction and sometimesin the opposite direction in different machines I provide for reversingthe connecting-arms E, so they may be made to project from one side ofthe hub A, as shown in full lines, Fig. 2, and in Fig. 1, or they may beadjusted to project from the opposite side of the said hub A, asindicated in dotted lines, Fig.2, so the attachment can be connected toproperly operate whether the fiy-wheel F be revolved in one direction orthe other. I also provide for connecting the arms E with the hub A, sothe said arms can in the knockdown position of theparts be turned intothe position shown in Fig. 3, in which they lie in a common plane saidhub and its center of movement, so that the'connectiug-arms E may beturned to project to one side of the hub A or'to the opposite side, aswill be understood from Fig. 2. It will also he noticed that the arms Emay be turned into the plane of the hub A, as shown in Fig. 3. At theirouter ends the arms E are provided with clasp portions E, which embracethe inner side of the rim of the wheel F, as shown in Fig. 1, andoperate to detachably secure the hub A firmly in connection with thesaid fly-wheel F. It will also be noticed that by connecting the arms Ewith the hub A by means of shanks E on the arms E fitting in the socketsA in the rim of the hub A, I am able to support the ends of the arms Eopposite the clasps E at a point more remote from the axis of the hub Ain any given size of hub than ifthe arms were secured to the side faceofthe hub, so that I am able to secure a stronger and better action ofthe connecting-rods E in their engagement with the fly-wheel, as will beunderstood from Figs. 1 and 2 of the drawings.

The blades B may be made of pasteboard or other suitable material havingthe shanks G, whoselends 0 may fit in the sockets A and may be adjustedtherein to suit the fan to the speed of the fly-wheel F, some operatorsdriving the machine faster than others, as is well understood.

By my invention it will be noticed I provide a fan attachment which canbe readily connected with the fiy-wheel and one in which the connectingspring-arms E, which may preferably be of resilient wire,can be adjustedinto the plane of the hub or to project from one side or the other ofsaid hub, as occasion may require, and in which the ends of said arms inconnection with the hub of the fanwheel are arranged as far as possiblefrom the center of said hub by fitting the shanks E of the saidconnecting-arms in sockets formed in the outer rim of the hub A, as willbe understood from Figs. 2 and 3 of the drawings.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. The herein-described improvement inand provided at their inner ends with shanks movably fitted in therim-sockets of the wheelhub whereby the said arms are connected with thehub at a point remote from the center thereof, and can be adjusted intothe plane of said hub or to project from one side or the other of saidhub, substantially as and for the purposes set forth.

2. The combination in a fan attachment of the hub provided in its rimwith sockets for the shanks of the fan-blades and with sockets for theshanks of the connecting-arms, the fan-blades having their shanksfitting in the rim-sockets of the hub, and the spring connecting-armsadapted at their outer ends for engagement with a fly-wheel of asewing-machine and having at their inner ends shanks fitting in thesockets in the rim of the hub, the said arms being adjustable into theplane of the hub or to project to one side or the other of said hub,substantially as set forth.
